Description:

BACKGROUND OF THE INVENTION

[0001] 1. Field of Invention

[0002] The invention relates to Bluetooth technology and more particularly
to a computer input device (e.g., mouse or keyboard) having a Bluetooth
arrangement for operating at least two computers by switching by
manipulating the Bluetooth arrangement.

[0003] 2. Description of Related Art

[0004] Bluetooth is a short distance wireless communication technology of
wirelessly transmitting information (e.g., text, voice, and/or video
data) within a range of 10 to 100 m with up to 1 Mbps.

[0005] A Bluetooth-enabled device (i.e., Bluetooth device) enters a
connect state for communication with other Bluetooth devices through the
states of inquiry or the like. In this process, the Bluetooth devices are
designated as a master and slaves according to their roles.

[0006] To establish a new connection between Bluetooth devices within the
range of each other, the devices must coincide in operation clock and
frequency pattern. In the inquiry state, a master repeatedly transmits
signals at a frequency to let slaves synchronize to the frequency
pattern.

[0007] U.S. Pat. No. 7,308,231 entitled "Computer mouse with Bluetooth
hand-free handset" comprises an electric source module for supplying
power to the computer input device, comprising a voltage step-up circuit
and a battery, in which the battery can be a one-time-battery or a
rechargeable battery used as the electric source for the computer input
device; an optical mouse circuit for detecting movement vector caused by
a movement of the computer input device; a Bluetooth module coupled to
the optical mouse circuit. The module is further connected to an antenna,
a power LED for indicating whether the computer input device is powered,
and a link LED for indicating whether the computer input device is in a
communication state; an echo cancellation circuit coupled to the
Bluetooth module for canceling echoes of audio signals; a sound receptor
coupled to the echo cancellation circuit for receiving audio signals; an
audio signal amplifying circuit coupled to the echo cancellation circuit
for receiving and amplifying the audio signals outputted from the echo
cancellation circuit; and a loudspeaker coupled to the audio signal
amplifying circuit.

[0008] Typically, a computer can be operated by manipulating a mouse or a
keyboard, and two mice or keyboards are required to operate two computers
respectively. However, the well known configuration is not convenient in
use. Thus, a need for improvement exists.

DETAILED DESCRIPTION OF THE INVENTION

[0019] Referring to FIGS. 1 to 3, a computer input device (e.g., a
wireless optical mouse) with a Bluetooth arrangement (hereinafter,
referred to as a Bluetooth mouse) in accordance with a first preferred
embodiment of the invention is generally designated by numeral 1A. The
Bluetooth mouse 1A comprises the following components as discussed in
detail below.

[0020] A housing 10 comprises a side opening 101, a top opening 102, and
four front openings 103. A PCB (printed circuit board) 12 is mounted on a
base 11.

[0021] An IC (integrated circuit) module 13 is electrically connected to
and mounted on the PCB 12. The IC module 13 comprises four LED
(light-emitting diode) indicators 131 mounted in the front openings 103
respectively, and a scroll wheel 132. A Bluetooth module 14 is
electrically connected to and mounted on the PCB 12. The Bluetooth module
14 comprises a push button switch (e.g., a two-section push button
switch) 141 and a Bluetooth signal transmission unit 142.

[0022] In an assembly state of the Bluetooth mouse 1A, the base 11 is
releasably secured to the housing 10 in a manner well known in the art.
Both the PCB 12 and the IC module 13 are mounted in the Bluetooth mouse
1A. The push button switch 141 projects out of the side opening 101. The
scroll wheel 132 is rotatably mounted in the top opening 102.

[0023] As shown in FIGS. 1 and 3 specifically, a user may manipulate the
Bluetooth mouse 1A in cooperation with a conventional keyboard 1B to
operate a plurality of computers (two are shown) 3. The computers 3 are
Bluetooth-actuated devices and each computer 3 corresponds to one of a
plurality of unique IDs (identifications) stored in the Bluetooth module
14 (i.e., stored in the Bluetooth signal transmission unit 142).

[0024] For example, prior to a switching operation, the leftmost LED
indicator 131 is lit and other LED indicators 131 are dimmed. That is,
the left computer 3 is being operated by the Bluetooth mouse 1A and the
right computer 3 is idle. Alternatively, the LED indicators 131 are
replaced with electronic display devices for showing decimal numerals in
other embodiments.

[0025] A user may press the push button switch 141 to switch the operation
from the left computer 3 to the right computer 3. In detail, after the
pressing the Bluetooth signal transmission unit 142 repeatedly transmits
signals at an operation frequency to let the computers 3 synchronize to
the frequency pattern. After a successful communication, the ID of the
left computer 3 is disabled and the ID of the immediately next computer
(i.e., the right) computer 3 is enabled. Moreover, the LED indicator 131
next to the leftmost LED indicator 131 is lit and other LED indicators
131 are dimmed. The user can identify which computer 3 is being operated
by the Bluetooth mouse 1A by observing brightness or dimness of the LED
indicators 131. Further, a quick switch operation is carried out.

[0026] Referring to FIGS. 4 and 5, a computer input device (e.g., a
wireless keyboard) with a Bluetooth arrangement (hereinafter, referred to
as a Bluetooth keyboard) in accordance with a second preferred embodiment
of the invention is generally designated by numeral 2B. The Bluetooth
keyboard 2B comprises a keyboard housing 20, a Bluetooth module 14
including a push button switch (e.g., a two-section push button switch)
141 and a Bluetooth signal transmission unit 142, and an electronic
display device 15 (e.g., a seven-segment display as shown).

[0027] In an assembly state of the Bluetooth keyboard 2B, the electronic
display device 15 is mounted on, for example, a right top corner of a top
surface of the keyboard housing 20 and the Bluetooth module 14 is mounted
beside the electronic display device 15 with the push button switch 141
being exposed.

[0028] As shown in FIG. 5 specifically, a user may operate the Bluetooth
keyboard 2B in cooperation with a conventional wireless optical mouse 2A
to operate a plurality of computers (two are shown) 3. The computers 3
are Bluetooth-actuated devices and each computer 3 corresponds to one of
a plurality of unique IDs stored in the Bluetooth module 14 (i.e., stored
in the Bluetooth signal transmission unit 142).

[0029] For example, prior to a switching operation, a decimal numeral "1"
is shown on the electronic display device 15. That is, the left computer
3 is being operated by the Bluetooth keyboard 2B and the right computer 3
is idle.

[0030] A user may press the push button switch 141 to switch the operation
from the left computer 3 to the right computer 3. In detail, after the
pressing the Bluetooth signal transmission unit 142 repeatedly transmits
signals at an operation frequency to let the computers 3 synchronize to
the frequency pattern. After a successful communication, the ID of the
left computer 3 is disabled and the ID of the immediately next computer
(i.e., the right) computer 3 is enabled. Moreover, a decimal numeral "2"
(i.e., increase in value) is shown on the electronic display device 15.
Alternatively, a default decimal numeral (e.g., "1") is shown on the
electronic display device 15 if the previously shown decimal numeral is
"2" which is the maximum value in this embodiment. The user can identify
which computer 3 is being operated by the Bluetooth keyboard 2B by
observing the decimal numeral change shown on the electronic display
device 15. Further a quick switch operation is carried out.

[0031] While a Bluetooth mouse and a Bluetooth keyboard are described as
preferred embodiments of the invention, it is understood that Bluetooth
earphones, Bluetooth loudspeakers, or other Bluetooth devices are equally
applicable without departing from the scope of the invention.

[0032] While the push button switch is described as a two-section push
button switch in the above preferred embodiments of the invention, it is
understood that a push button switch having at least three sections are
equally applicable without departing from the scope of the invention if
there are at least three computers to be operated.

[0033] It is envisaged by the invention that a computer input device
incorporating a Bluetooth module of the invention is adapted to operate
more than one computer by switching. This is a significant contribution
of the invention to the advancement of the art which, as discussed in the
background section and for example, two mice or keyboards are required to
operate two computers respectively.

[0034] While the invention herein disclosed has been described by means of
specific embodiments, numerous modifications and variations could be made
thereto by those skilled in the art without departing from the scope and
spirit of the invention set forth in the claims.
